Some changes have been taking place at Rare Steakhouse, 833 E. Michigan St., including the departure of one partner and the hiring of a new chef.

Jack Sosnowski, who had been the public face of Rare, sold his share of the Rare restaurants Feb. 15 to his business partners, Mark Burish, a founder of the Hurley, Burish and Stanton law firm in Madison; Adam Burish, Mark’s son and a former National Hockey League player; and Tim Neuville, a friend of Mark Burish’s since high school.

Sosnowski, who has four other Madison-area restaurants, also has three children younger than 5, Mark Burish said, and the sale allows him to stay in Madison and spend more time with his family.

Besides the Milwaukee steakhouse, Rare has its original restaurant in Madison and a steakhouse that opened in Washington, D.C., in November.

At the Milwaukee restaurant, Sunday hours have ended and a new lunch menu focused on value and lighter fare is set to debut in April, Burish said.

The restaurant has hired a new executive chef: Aaron Schmude, who has worked in Las Vegas and D.C.

“If I had to describe my style, it’s taking familiar, approachable dishes and then putting a little modern twist with different flavor profiles and complimentary ingredients,” Schmude said in a written statement.

And Rare has hired an assistant general manager: Joshua Wolter, the general manager of c.1880 in Walker's Point, will join the steakhouse in mid-April.

Wolter said he'll be pulling double-duty for a time, assisting at c.1880 until it serves its last dinner April 28.
